Abstract
The present invention is directed to variable resistance zones for sensing input to an electronic device, as well as ministops for controlling deformation of the input components to ensure the accuracy of the inputs sensed. In one embodiment, a system in accordance with the present invention includes multiple variable resistors, an actuator, and a converter. The actuator overlies the multiple pressure-sensitive variable resistors and is configured to generate a pressure at a contact location on the multiple variable resistors. The converter is coupled to the multiple variable resistors and is programmed to map a pressure at the contact location to a pressure, location, or both along the surface of the actuator.
